ABINGTON, Pa. (CBS) — Abington police are hoping surveillance video of an armed robbery early Monday morning at a McDonald’s on Old York Road will help them find the three men who held up the fast food restaurant.

Police say it was just after 6am when two men, at least one armed with a handgun, burst into the store and announced a holdup while a third man served as lookout.

Investigators say one of the men stayed up front with the employees while another went to the office and forced the manager to open the safe.
